| The invention relates to a baked refractory ceramic product. According to the invention, both shaped and unshaped products come within this generic term. Shaped products are those which have a defined shape, so that they can be ready-made at the manufacturer's premises. The shaped products include: bricks, nozzles, tubes, stoppers, plates, etc. The products categorized as unshaped products include those which are usually produced at the user's premises from a suitable material. These include bottoms of furnace assemblies which are cast from a material, but also repair materials, etc. | ||||||
| 202 | Reinforced Resin-Derived Carbon Foam | US12796526 | 2010-06-08 | US20100308280A1 | 2010-12-09 | Douglas J. Miller; Irwin C. Lewis; Richard L. Shao; Mehmet Suha Yazici |
| A reinforced carbon foam material is formed from carbon fibers incorporated within a carbon foam's structure. First, carbon fiber bundles are combined with a liquid resol resin. The carbon fiber bundles separate into individual carbon fiber filaments and disperse throughout the liquid resol resin. Second, the carbon fiber resin mixture is foamed thus fixing the carbon fibers in a permanent spatial arrangement within the phenolic foam. The foam is then carbonized to create a carbon fiber reinforced foam with improved graphitic characteristics as well as increased strength. Optionally, various additives can be introduced simultaneously with the addition of the carbon fiber bundles into the liquid resol, which can improve the graphitic nature of the final carbon foam material and/or increase the foam's resistance to oxidation. | ||||||
